* Measurements of capacitance of 0.5μ or more shouldn’t be repeated at
10000V/ 12000V Ranges in a short time. (Rough guide: 5 times/ hour)
* A message “Noise Error” may be displayed on the LCD and a measurement
may be ceased at 10000/12000V Ranges. In this case, select a lower Voltage
Range and test again.
